Ok so I aquired a battery to day 100 amp hour sealed approx 22" x 11" x 5" Brand new still wraped and wheighs in at around 70lb's
Anyway I assume(not sure why) this is a deep cycle battery??? and would be no good to run the Warn 8274, if this is the case, then it would not like running the starter motor to often either???
So I can't see me buying a fridge for the 40 as I'm out of room already. Would this be good for a "emergency" start and run/emergency boost for winch, just to get out of the brown sticky stuff or is it no good for nothing and should be sold while new and put the cash towards the right thing.
Deep cycle batteries work for starting and winching, they just don't last as long in that application as they do in the one for which they are designed ie slow, deep discharge. They are probably not as effective at providing a lot of amps in a hurry either.
Free is a pretty good price, but I think I'd try to sell it and get a starting battery if that is what your application calls for.
From the PDF it looks like it was made for UPS use. For winching you'd want a pair of them or at least run the engine/alternator at the same time. For refrigerator use it looks perfect. It is an AGM battery so most vehicle alternators are not setup properly to charge it. Consider a DC to DC charger made for AGM batteries, or just hook it up if you don't mind it getting killed early in it's life. At the absolute minimum I would hook it up with a battery isolator. You don't want to mix battery types or ages in a connected circuit without isolation when not charging. If you do mix them they can kill each other through discharge from the higher voltage one to the lower voltage one. PS, don't even think of shorting the terminals. It could turn a tool into a fusible link. For paralleling batteries, search on "dual battery".
Before putting it in you vehicle, I'd test it out to see if it is still good. Charge it fully with a battery charger designed for AGM batteries. A battery charger designed for flooded lead acid batteries can damage an AGM battery by boiling away the limited amount of water. Once fully charged discharge it with a load like a few tail lights. Use a DVM to determine the Amp load each tail light draws then add em up for the total load. I'd aim for 10 Amps draw. Compare how long the battery lasts with that load to the chart. If it is anything above 80% of design capacity you got a real deal.
I'll research AGM batteries next and get it set up properly. I was thinking of trying to keep it on charge when the moter is running use it for the lights when camping and if needed (emergency) parralel it to the main start/winch battery, via a Anderson plug (lots of those in the shed)
I have no worries that it's good, if not I'll go back and swap it for another as I see hundreds of these in a year but not many spare's.
As for two of these to run the winch I cant think where to put them at the moment so I will keep thinking on that one.
But so far today it's been too hot so took the roof off the 40 folded the screen down and found the only rust free area on the whole truck!!!!!!!!!!!!!
Just saw the weather forecast and it's wet so the roof's going back on.
